I doubted I could stop drinking as well. Until I realised I had a major problem with it and forced myself to get help with a Detox Service. It worked. Not for everyone, but it did work. About your other problems, being like a robot or very cold/distant.. seems to me (I could be wrong)-as if you are erecting a 'shield' so that you don't get hurt. Because you have been hurt before? Just guessing here. Just want to try and help, that's all. Hope you find that help.
